The CorkSport Advantage

Mazda 6 turbo Downpipe upgrade

Fitment Focused:

The CorkSport Downpipe is designed to fit just like an OEM downpipe, while flowing much better! We used 3D scan data of the stock downpipe to CAD design our two piece downpipe to ensure perfect fitment with the turbocharger and OEM or aftermarket exhausts. The two-piece design also provides an easy install as you won’t have piping in the way when tightening the mounting bolts!

Bonus Power Potential:

The CorkSport downpipe offers bonus power potential for your Mazda 6 turbo. By eliminating the poorly bent 65mm piping of the OEM downpipe and the large catalytic converter, the CorkSport downpipe offers minimal restrictions and greater peak flow. The cast bellmouth provides a smooth transition from turbo to piping, with 80mm piping providing enough flow to efficiently support 500+ HP. Check out the release blog for more details!

Options to Suit Your Build:

The CorkSport Mazda 6 downpipe is offered in both fully catless and a high flow cat setup to suit your preferences for your build. Fully catless setup will offer the best in performance while the 300cel high flow cat offers minimal restriction but without the added smell of a catless vehicle. As replacing/removing your catalytic converter is illegal in most areas, the CorkSport downpipe is sold for off-road or race use only.

Materials & Manufacturing:

Each CorkSport downpipe is produced using high quality materials and manufacturing processes. At the turbo, a cast 304 stainless steel bellmouth is used for its durability and flexibility in manufacturing. The OEM piping is replaced by 80mm mandrel bent and TIG welded piping again for long lasting durability. The sections are joined together using CNC machined v-band flanges for a leak free seal.

Hardware and Accessories:

Included with your downpipe is everything needed for installation, plus a few extras! The OEM turbo studs are very long and are prone to breakage as a result, so we supply brand new high strength turbo studs and crimp nuts. Also included is new hardware and a Remflex gasket for the downpipe to exhaust connection. A supplied stainless v-band clamp keeps the upper and lower downpipe sections securely connected. We even include a custom heat shield to fit the CS downpipe to keep all other engine bay components safe.

  • For off-road & race use only.
  • A check engine light (CEL) will be illuminated on catless and some catted setups as a result of installation.
  • We recommend a tune after installation of the CorkSport Downpipe. While the car will operate without damage, you may experience some surging or “hiccups”, especially at wide-open throttle. This is simply the car hitting airflow & torque limits in the ECU and pulling power back.

Additional Features

  • Vehicle Fitment: 2018-2022 Mazda 6 2.5T FWD Automatic Transmission.
  • Designed & Developed in America: Designed, tested, & validated in Vancouver Washington, in the Pacific Northwest.

Sounds great, exhaust notes are deeper and louder. You can hear the turbo spooling the second you step on the gas. 4/5 rating because install was 6+ hours !

Since the 2019 CX-5 with the 2.5T, and the Mazda6 share the same platform, would it fit in the CX-5 with the same engine? Was this something that never was test fit, or was proven to not fit through testing. Would it be possible to test fit/develop one for the CX-5 with the 2.5t?

I see that the down pipe won’t directly fit to the 2019 Mazda Cx-5 turbo but how difficult would it be to mend it and create space so it does fit?
